The Pythagorean theorem works only for right triangles, where one angle is exactly 90 degrees. It is widely used in geometry, construction, navigation, surveying, and screen-size calculations whenever you need to find a missing side from two known sides.
Only for right triangles where one angle is exactly 90 degrees.
Use c = square root of (a squared plus b squared).
Use a = square root of (c squared minus b squared), or b similarly, where c is hypotenuse.
It is used in construction, surveying, navigation, design layouts, and engineering geometry.
